Figure 3From: Cysteine protease activation and apoptosis in Murine norovirus infectionCaspase activation after MNV-1 infection based on labeling of active proteases in live cells. Individual classes of caspases were assayed for activity by labeling with membrane permeable covalent activity-based probes coupled to a fluorescent dye (n = 3). Activation is reported in relative fluorescence units.Back to article page
